Answer:
25km ph
Step-by-step explanation:
A) Pine Road and Oak Street form a right angle, so we can extract the relation
where
is the distance we want to find (bottom side of the rectangle).
Alternatively, we can use the other given angle by solving for
in
but we'll find the same solution either way.
b) Pine Road and Oak Street form a right triangle, with Main Street as its hypotenuse. We can use the Pythagorean theorem to find how long it is.
Let
be the length of Main Street. Then
but of course the distance has to be positive, so
.
The total of all angles of a heptagon is 900.
Therefore
x+125+119+117+145+133+140 = 900
x+779 =900
x= 900-779
x =121 degrees
Answer:
∠E = ∠F = 41°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
x + x + 98 = 180 ( subtract 98 from both sides )
2x = 82 ( divide both sides by 2 )
x = 41
Hence
∠E = ∠F = 41°
The answer to the following equation is the first one.
